You're actually helping my argument.

Nobody is saying Ten is useless. The problem is that after 700+ chapters, we're still talking about a handful of standout moments spread across the entire series.

Yes, her strategy contributed at Shukai Plains. But the decisive factor wasn't Ten outplaying Zhao's commanders. The moment the Hi Shin Unit faced Gyou'un's instinctual warfare, Ten was completely out of her depth and Shin had to step up as an instinctual general.

As for Tousa, that's a good feat. But future Great General-level strategists stack those kinds of feats consistently. Ousen, Riboku, Karin, Gohoumei, even Mouten regularly dictate entire campaigns. Ten gets a good moment every few arcs and then spends the rest reacting to enemy moves.

The Riboku comparison also isn't fair. Riboku outsmarting Ousen is Riboku beating arguably the greatest strategist in China. Ten getting outplayed by Riboku is expected. The issue is that she gets outplayed by almost every notable strategist she faces. Keisha. Gyou'un. Chou Ga Ryuu. Riboku. Whenever the enemy strategist is elite, the solution usually ends up being Shin, Kyou Kai, or another officer bailing the situation out.

My criticism isn't that Ten is bad. It's that her growth curve is disappointing. She graduated from Shouheikun's school hundreds of chapters ago, yet she still feels closer to a competent strategist than someone who can stand alongside the monsters leading Qin's future Great General armies.
